The reason is that for the most part, people do not have the time or patience to decipher what a person is trying to say and in a world of digital attention deficit disorder...

Perhaps it is exactly the problem to change the world. To try to make the most simple of changes in this world. Dealing with a fauna which do not have the time or patience to decipher anything. ¿What do we have left then?

Or we success separating away the grain of the straw inside this distracted, misdirected and disoriented humanity to form at least a minimum army of conscious beings capable to bring new, active and useful feedback from the meaningful teachings and messages they have been exposed to, or we simply perish.

What's the point to repeat briefly like parrots what everyone and their pets are all saying again and again endlessly with the same babbling words?

Does everything we do has to be always selfishly interested for our own short lived benefit only?

There are some who already have seen enough in this life. And they are well aware that they don't have much time left to keep trying. :)
